sPEcIFioAirIoN forming part of Letters Patent No. 645,519, dated March 13, 1906.

Application filed January 20,1399. Serial No. 702,762. (No model.) i

To all whom it may ooncernr Be it known that I, WILLIAM H. BRACE- WELL, of Fiskdale ,county of Worcester, State of Massachusetts, have invented an lmprove ment in End-Holders for Spindle-Bands, of

which the following description,in connection from the strain due to the pull of the cylin-.

der, as bands are usuallyput on when the frame is running, and, second, the measuringof the strain on the band by a suitable springscale enables the operative to determine how much tensionis being exertedas the band is applied, so that the desired tension can be applied when the band is tied.

Figure 1 is a perspective View of a portion of a spinning-frame, including the spindlerail, the spindle-driving cylinder, and a spindle, the end-holder embodying myinvention being shown in use as the band is about to be tied. Fig. 2 is a side elevation, partly in section, of the end-holder; and Fig. 3 is an inner face view of one of the end-holding jaws or gripping members.

The spindle-rail A, spindle S, having a sleeve-whirl WV, the spindle-base B, and the spindle-driving cylinder or drum 0, Fig. 1, may be and are all of well-known or usual construction in spinning-frames.

The band-end holder embodying my invention comprises, essentially, two relativelyn1ovable and yieldingly-connected members, one of which is adapted to engage and hold one end of the band passed around the cylinder, While the other member is held stationary by engagement with the spindle-base or any fixed part of the frame, whereby the operative, with both hands free, can adjust the tension of the band and tie its ends together. Referring to Figs. 1 and 2, the member 'ctis shown as a tube having a laterally-extended projection or hook a" and a longitudinal slot a Fig. 1, with a preferably-threaded lower end a to receive a tubular protective cap a Longitudinally movable within the member ct I have mounted the baud-holding member 1), shown as a rod shouldered at its upper end at b to rest against the adjacent end of the supporting member a and having its op"- posite end extended beyond the member a and threaded at 6 Fig. 2, to receive an adjustable nut b between which and the threaded end a of the member cta spiral spring 5 surrounds the shank of the holding member. A

pin or stud 1), fast on the member I), is extended laterally through the slot a and carries a pointerb which cooperates with a scale M on the exterior of the member a, the spring 8 normally holding the shoulder h against the end of the member a with the pointer at zero of the scaleM. The member Z) is provided with an elongated open head Z), at the opposite sides of which jaws b are fulcrumed nearer its outer end at 6 the jaws having their opposed and convex faces toothed or corrugated and offset to extend beyond the head, preferably at one side, as at b", as shown in. Fig. 1, the jaws being inclosed within the open head and of such length that they cannot be moved outward one past the other.

When it is necessary to tie a spindle-band, the operative inserts between the laterallyprojecting portions 1) of the jaws b that endt of the band 25 which will be subjectedto tension by the pull of the cylinder C and catchesthe hook a of the member a, preferably around the spindle-base B below the Whirl. The free end t of the band is then grasped by the operative and pulled until the pointer 12 indicates by its position on the scale M the tension desired, and the knot is tied, it being understood that when the free end of the band is strained the member I) will move relatively to the member a, the spring 8 being compressed proportionately to the strain. The

scale M can be readily graduated to indicate 9 tensile strain on the band in pounds, and when the desired tension is indicated the operative ties the ends of the handy together. By a slight lateral pull'away from the side of the holding device toward the spindle the band is readily released from the jaws b and then the device is unhooked from the spindle-base. 7 The greater the pull on the band when engaged by the jaws the more firmly will they hold it, as they are thus drawn toward each other, the strain being transmitted through their fulcra to the sliding member b.

By moving the nut 12 the tension of the spring 5 can be adjusted as desired, while the cap a protects the spring from injury and serves as a handle for the device.

My invention is not restricted to the corn struction and arrangement shown, for, so far as I am aware, my invention is broadly new.

Having fully described my invention, What Iclaim, and desire to secure by Letters Patent, is-

1. An end-holder for spindle-bands, comprising relatively-movable members, clamp? ing-jaws carried by one member and adapted to engage the band end and an open hook on the other member, to be temporarily held by a fixed objectg and a yielding connection betWeen said members, the relative movement of saidfmembers being determined by the pull or strain of the band. j

'2. An end-holder for spindle-bands, com?- prising a member having a rigidly-attached, laterally-extended hook adapted to engage a spindle-base, a cooperating member movable longitudinally, a clamping device thereon to engage the band end, a spring connecting said members and resisting their relative longitudinal movement, and means mounted'on the movable member to adjust the tension of the spring.

3. An end-holder for spindle-bands, comprising a tubular member having'a hook eX- tended laterally therefrom, a cooperating member extended through and longitudinally movable in the tubular member atone end thereof, clamping-jaws on the movable member, and a spring at the other end and connecting said members and adapted to resist their relative longitudinal movement.

4. An end-holder for spindle-bands, comprising relatively-movable members, one of said members having a laterally-extended hook thereon, an open head on; the other member, clamping-jaws mounted on said head to swing within it and extended laterally beyond it, a spring connecting and adapted to resist relative movement of said members, and means to measure the extent of such movement.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. WILLIAM H. BRAGEWELL.
